- Member of the Texas Instruments
Widebus? Family - Operates From 1.65 V to 3.6 V
- Inputs Accept Voltages to 5.5 V
- Max tpd of 4.4 ns at 3.3 V
- Output Ports Have Equivalent 26-Ω Series
Resistors, so No External Resistors are Required - Typical VOLP (Output Ground Bounce)
<0.8 V at VCC = 3.3 V, TA = 25°C - Typical VOHV (Output VOH Undershoot)
>2 V at VCC = 3.3 V, TA = 25°C - Ioff Supports Live Insertion, Partial-Power-Down Mode,
and Back-Drive Protection - Supports Mixed-Mode Signal Operation on All Ports
(5-V Input/Output Voltage With 3.3-V VCC) - Bus Hold on Data Inputs Eliminates the Need for
External Pullup or Pulldown Resistors - Latch-Up Performance Exceeds 250 mA Per JESD 17
- ESD Protection Exceeds JESD 22
- 2000-V Human-Body Model (A114-A)
- 200-V Machine Model (A115-A)
- 1000-V Charged-Device Model (C101)
This 16-bit buffer/driver is designed for 1.65-V to 3.6-V VCC operation.
The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
The SN74LVCH162244A device is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
